SPOOL.

SPEGIFICATIQN forming part of Letters Patent No. 599,035, dated February 15, 1898. Application filed October 20, 1897. Serial No. 655,772. (No model.)

To all whom, it may concern:

Be it known that WG,'ALFBED J. COX and FE- LIX D. LINK, citizens ofthe United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Spools, of which the following is a specification. Our invention relates to that class of large spools which are employed in yarn-mills and in other branches of the textile industry.

The object of our invention is to provide a strong, simple, and inexpensive construction for securing the spool-heads rigidly to the barrel of the spool, so that these parts will not be liable to twist or become loose with respect to each other.

To these ends our invention consists of the parts and combinations of parts, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a partial side view, partly broken away, of a spool constructed according to our invention. Fig. 2 is an enlarged view of the fastening device which we preferably employ, and Fig. 3 is a perspective view of the fastening-washer.

The life of the large spools employed in different branches of the textile industry usually depends on the firmnessof the connection be. tween the barrel and the head of the spool.

In practice these spools are subjected to hard usage, and i t frequently happens that thehead of the spool will become loosened or free to turn with respect to the barrel thereof. When the head of a spool is free to turn with respect to its barrel or when there is any looseness between these parts, the relative motion of the head with respect to the barrel of the spool will break or rough up the yarn which may be wound on the end of the barrel. This fact has led textile manufacturers to discard a spool as soon as its head becomes at all looscried, and on this account spools have to be frequently renewed, and many spools are now discarded which are but slightly worn.

The especial object of our invention is therefore to provide a fastening device which will secure an absolutely rigid connection between the head and body portion of the spool and which may be used for repairing the spools in which the heads have worked loose.

A'spool constructed according to our invention comprises a barrel, a head, a central mehead B. Fitting into a transverse socket in the barrel A is a cylindrical nut 10. Aspindle 11 is threaded into the nut 10 and is provided with a shoulder 12 and an extending gudgeon 13. Mounted on the spindle 11 and countersunk to "receive the head 12 is a securing-washer 14. The securing-washer 14: is pronged or is provided with two inwardly-extending sets of projections, as 15 and 16. The outer set of projections 15 is arranged to engage the head B, while the inner set of proj ections 16 is arranged to engage the barrel A.

In practice the washer 14 is provided with three projections 16 for engaging the barrel and with four projections 15 for engaging the head, and we prefer to ,arrange the projections, as shown, so that they will not be directly opposite each other and will have less tendency to crack or split the wood.

In assembling a spool constructed according to our invention the spool is mounted in a lathe, the gudgeon '13 is secured in astationary clamp or chuck, and the barrel A of the spool is turned so that the screw-threaded spindle 11 will bedrawnin and the prongs of the securing-washer willbe firmly forced into the barrel and head of the spool, respectively.

One especial advantage in the use of a securing device constructed according to our invention resides in the fact that the same is especially adapted for repairing the spools which have been discarded on account of the loosening of their heads, and in practice we make the spindle l1 and nut 10 somewhat larger than the corresponding parts now employed in spools, so that the barrels of existing spools can be counterbored to accurately receive these parts.

We are aware that changes may be made in the construction of our spools without departing from the scope of our invention as expressed in the claims. We do not wish, therefore, to be limited to the form which we have shown and described; but

Vhat we claim, and desire to secure by Letters Patent of the United States, is

1. An article of manufacture consisting of a pronged securing-washer for fastening spoolheads, comprising a body portion having two concentric sets of projections 15 and 16 extending from the inner face thereof for engaging the head and barrel of a spool respectively, substantially as described.

2. In a device of the class described, the combination of a barrel A, a head B fitting thereon, a nut 10 mounted in the barrel A, a
